GOLLAPSIBLE BABY CARRIAGE.

Application filed December This invention relates to anew and improved collapsible baby carriage. 1

One of the objects of this invention is to provide a baby carriage having a framework which is readily collapsible and which is rigid and strong Whenit is in the ex tended position. 7

Another object of this invention is to provide a device ofthis character which shall be simple and cheap to construct.

Another object of this invention is to provide a device of this character having an improved awning frame which is so mounted that it does not substantially increase the bulk of the device when it is in the collapsed condition.

Other objects of this invention will be set forth in the following description and drawings which illustrate a' preferred embodi ment of this invention, it being understood that the above general statement of the objects of our-invention is merely intended to generally illustrate the same and not to limit it in any manner.

Fig. 1 is a side elevatiomthe device being shown in the extended position.

' Fig.2 is atop view of Fig. 1.

Fig. 3 is a rear elevation-of Fig.1, apart of. the upper or awning structure being omitted for thesake of clearness.

Fig. 41 is a side elevation of the device in the collapsed condition.

Fig. 5 is a front elevation of Fig. 4.

Fig. 6 illustrates a detail of the connecting .means between the awnin frame and the carriage frame, the sai connecting means being shown in the'closed or con: nected position.

Fig. 7 is a view similar to Fig. 6, the said connecting means being shown in the open or unconnected position.

The device comprises a. hammock 10 made of any suitable fabric, which is connected to two U-sha-ped rails 19. The rails 19 are revolubly connected by means of pins 21 to intermediate connecting members 20. These connecting members 20 each have a U- shaped cross-section. Hence, when the device is in the position shown in Fig. 1, the rails 19 cannot be moved downwardly because the top portions of their adjacent ends abut the underside of the connecting member 20. However. the hammock 10 can be readily collapsed by moving the connecting members 20 upwardly.

Leg members 13 and 12 are pivotally con- 9, 1925. Serial No. 74,244..

nected to each other by means of pins 22. The leg members 13 are also pivotally connected to one of the rails 19 by means of pins 13. and the legs 12 are also pivotally connected to the other rail 19 by means of pins 15. As clearly shown, for example, in Fig. 11, the legs 13 and 12 are provided with offset U-shaped portions at their upper ends. The bottoms of the legs 13 are integral with a cross-member 13. a

As shown in Fig. 5, the legs 12 are inte gral with a straight bottom cross-brace 12. Bearing members 2% for the axle 26'are riveted to the bottoms of legs 12, which are inwardly bent,as shown in Fig. 5. Front wheels 28are connected to axle 26.

The bottoms of legs 13 are integral with a cross-brace 13. The bottoms of legs 13 are not inwardly bent. Rear bearing members 223 are connected to the bottoms of legs 13. The central portion of brace 13 is offset and a central bearing member 32 is connected thereto. A rear axle 25 is mounted in rear bearing members 28 and 32 and rear wheels 27 are connected to rear axle 25.

Awning supports 15 are pivot-ally connected to the offset upper portions of legs 12 by pins 31. The awning supports 15 can be maintained in alignment with legs 12 by means ofscrews 29 whose shanks project through openings 29 inlegs l2, and also extend through L-shaped slots 30 in awning supports 12. Wing nuts Nserve'to clamp the awning supports 15 to the legs 12. By loosening the wing nuts N and shifting the screws 29 to the lateral branches of slots 30, the awningsupports 15 can be swung clear of legs 12, as shown in Fig; 7.

A. U-shaped awning frame member 14:15 pivotally connected to theawning supports by pins 11. The awning supports 15 are connected to handle 17 and they are also connected by 1111-1211 brace 16. The awning fabric 17 is mounted in the ordinary manner on member 1a and brace 16.

Hence, the carriage can be collapsed by merely pulling upwardly upon the members 20. The awning members can be swung downwardly, into the position shown in Fig. 5, by detaching them from legs 12. The carriage then occupies a minimum amount of space so that it can be readily transported. It is not necessary to detach the nuts N from the screws 27 in order to free the awning frame from the legs 12, because merely loosening said nuts is sufiicient to enable the user to move the screws 27 to the lateral branches of slots 30.

in the collapsed condition, the height of the device is equivalent to the height of the legs. Since the awning supports 15 are then substantially parallel to the legs 12 and 13, the device has maximum strength in the collapsed position to withstand the shocks incident in shipping it, because all the metal parts are close to each other. The front axle 26 is shorter than the rear axle 25, so that the front wheels 26 are intermediate the rear Wheels 2?, when the device is collapsed. Hence, the device can stand and have substantial stability, when it is in the collapsed condition.

The proper offset arrangement of front wheels- 28writh respect to rear Wheels 27 is facilitated by the inward bend of the bot us of legs 12. A lateral brace 33 is provided asshown in 5. It is obvious that the safety strap ordinarily used in carriages an be connected tothe frame of the hammock adjacent the members 20, so that it will serve a handle when the carriage is collapsed, Since the bottoms of legs 12 are inw rdly bent or oifset, the hubs of the wheels can be located very close to the adjacent portions of the legs to which they are connected, as is shown more particularly in Figs. 3 and 5.

A preferred embodiment of the invention has been shown, but it is clear that numerous changes and omissions could be made Without departing from its spirit.

lVe c aim:

l. A collapsible carriage comprising a flexible hammock portion connected to rail members, said rail members having their adjacent ends pivotally connected to intermediate members having a substantially U- shaped cross section, leg members pivotally connected to said rail members and'to each other, and axles provided with Wheels connected to said leg members. the rear legs having awning supporting means pivotally connected thereto, and releasable clamping means adapted to rigidly connect said awning supporting means to said rear legs;

2. A collapsible carriage. comprising a collapsible hammock portion and having a handle, leg members pivotally connected to each other and to said hammock portion, awning supporting means pivotally connected to one of said leg members, said awning supporting means being connected to th handle of the carriage, a cross brace adja cent said handle and stiffenin said awning supporting means, awning fa bric mounted on said awning supporting means and said still'ening brace, and releasable clamping means adapted to rigidly connect the a'\vn ing supporting means to the adjacent leg member.

3. A collapsible carriage comprising acollapsible hammock, leg members pivotally connected to each other and to said hammock, a U-shaped awning supporting member connected to one of said leg members, said leg member being provided with longitudinal slots and said awning supporting member being, provided with adjacent L- shaped slots, screws having shanks projecting through the slots of said leg member and said awning supporting means, nuts adapted to cooperate with said screws, a lateral stiffening brace connected to said awning supporting means, awning fabric mounted on said awning sup-porting means and brace, and a carriage handle connected to said awning supporting means a. A collapsible carriage compriing. a collapsible hammock portion, and front and rear leg members pivotally connected to each other and to said hammock portion, said front and rear leg members each comprising two longitudinal portions integral With a bottom cross brace, one of said leg members having its bottom portion inwardly bent at both ends thereof so that it is inwardly offset with respect to the bottom portion of the other of said leg members, bearing members connected to the bottoms of the said leg members, axles mounted in the said hearing members, the said axles having Wheels mounted to turn closely adjacent the bottom portions of their respective leg members.

In testimony thereof We atfi-x our signatunes,
